Example Embodiment

[0029] Example 1

[0030] Mix 50 kilograms of 3A molecular sieve raw powder, 20 kilograms of kaolin, 15 kilograms of attapulgite clay, and 15 kilograms of bentonite, and transport them to the rotary automatic ball forming machine, and add 0.5 kilograms of water-soluble adhesive carboxymethyl cellulose. It is soluble in water and diluted with appropriate amount of water. While spraying the adhesive water solution continuously, the pellets gradually grow up and are formed into a molecular sieve body with a certain particle size. Then, 0.1 kg of the added compressive strength enhancer potassium silicate is dissolved in 10 kg of water, and the prepared potassium silicate aqueous solution is sprayed on the molded molecular sieve body to coat and strengthen it; then transfer to a special granular Dry for 20-40 hours in a natural energy drying car, and then use compressed air in a powder blower to blow off the dust and polish; roast in a roasting furnace at a temperature of 480-700°C for...

Abstract

The invention is a hollow glass desiccant and process for preparation, which belongs to desiccating agent of zeolite molecular sieve, particularly relates to a hollow glass desiccant and process for preparation, which comprises the steps as follows: 3A molecular sieve original powder 50.0-8.0.% and clay 20.0-50.0% are mixed to form main component, then water-soluble adhesive agent 0.1-5.0% (Wt%) and proper amount of water which calculate the main components by percentage by weight are added for balling and pelleting, and water solution of compression strength reinforcing agent 0.1-5.0% (Wt%) which calculate the main component by percentage by weight is sprayed on a balling billet body, then the balling billet body is covered, reinforced, dried in nature, blown, and polished and baked at 480-700 DEG C for 2-6 hours, finally the desiccant can be obtained. The desiccant components of the invention are reasonably matched, the preparation is novel, the structure of the device is simple, and energy is saved. The hollow glass desiccant which is made achieves an idea effect in some aspects of the technical indicator of special requirements for hollow glass desiccant such as compressive strength, powder dropping rate and selective adsorption for each air component and the like.

Description

technical field [0001] A hollow glass desiccant and a preparation method thereof belong to zeolite molecular sieve desiccants, in particular to a hollow glass desiccant and a preparation method thereof. Background technique [0002] Hollow glass doors and windows are used in transportation tools such as vehicles and ships and fixed buildings, which is a great initiative for human beings to save energy and protect the environment. The thermal conductivity of air is low, and the air embedded in the insulating glass makes an outstanding contribution to its thermal insulation performance, but the physical properties of the air and the small amount of moisture that enters the insulating glass interlayer change with the change of temperature, which also brings new problems to the manufacture and use of insulating glass. A lot of trouble. When the ambient temperature drops below the dew point of the moisture in the insulating glass interlayer, dew condensation or even frost will f...
